Summary0002365: computer sometimes crashes/hangs on Scanning ISA $0290
DescriptionSometimes, but not always, Scanning ISA bus causes computer to lock up. Is there any very low level logging I can enable?
Steps To Reproduceunable to consistently reproduce.

I'm on 4.51.

I can control the CPU fan and SysFan for this motherboard.

Sometimes during Speedfan startup (on completely idle, completely-finished-booting computer), Speedfan appears to cause the computer to hang requiring a hard power-off.

Generally this occurs at the 'Scanning the ISA bus' point. I'm interested if there are any steps I can take to solve this problem.

/nosmartscan or whatever the flag is happens later in the startup process than these locks.

Sometimes I get similar hard-lock-ups, which also seem completely random, when Speedfan is just running in the background.
TagsNo tags attached.
Motherboard ModelGA-970A-UD3P

I discovered and pulled 2 bad sticks of PNY RAM both of which individually were erroring in further memtest testing. I have returned to using Speedfan and will report if this problem happens again in the future.

I think if it were going to happen by now it would have happened by now-- so everything appears to be working. Thank you for the wonderful software!!!

I am glad to read that, somehow, SpeedFan helped to detect bad memory. This is an unexpected feature :-)
